CR 3400 (In-Mould Epoxy Gelcoat / Surfacing System)
- Easy to sand
- May also be used with some Gurit prepregs
CR 3400 is an in-mould epoxy surfacing system for epoxy laminates, and is designed to be used as the base for the subsequent application of a paint scheme. CR 3400 is therefore formulated to be easily sandable so that once released, the CR 3400 surface can be readily keyed prior to the application of the paint system. This feature gives additional benefits in that any minor surface defects caused by laminate print-through or mould imperfections can easily be sanded away.
CR 3400 is applied into a mould in the same way as other epoxy gelcoats, and has similar handling characteristics. However, the product has a considerably longer overcoating window than other gelcoats - up to one day with Standard hardener at 20°C. This means that the system can also be used in a very flexible manufacturing environment.
CR 3400 is designed to be backed up with Ampreg 22 and Ampreg 26 epoxy laminating systems. Under certain conditions it may also be used in conjunction with SP SE70, SE84 prepregs, ST70 and ST 95 SPRINT® systems. CR3400 must be painted prior to water immersion.

Bisphenolic gelcoats have the maximum heat and chemical resistance compared to all gelcoat groups. Therefore these gelcoats are widely used in chemical industry where high temperature and chemical resistance is necessary.
Polijel 291 is a bisphenolic based, thixotropic, high reactive gelcoat.
It is used for top level chemical and temperature resistant applications.
The most important feature of gelcoat is not effected many chemicals even at high temperature.
Polijel 291 is used especially production of industrial process equipments, chemical tanks, mould production and for surface coatings againts corrosion.
To obtain the maximum resistance levels avoid using pigment and filler much.

The gelcoats in this group are designed for general industrial applications. They are suitable for economic applications where weathering, water or chemical resistance is not necessary for the products that will be used indoor or paint finish.
Polijel 208 is an orthophtalic based, thixotropic, preaccelerated, general purpose gelcoat.
It's used especially in the production of sanitary equipment, playground equipment and in the automotive industry where the parts will be painted after production. It can also be used in interior decoration and polyester furniture production.
Polijel 208 shouldn't be preferred when aesthetic appearance, water and chemical resistance are needed because it gets matt and yellow in the course of time.

These gelcoats are specially designed for mold building applications where impact, heat and chemical (aging effects of release agents) resistance is at high levels. Polijel 220 series are optimized to work with Polipol 320 Resin for mold production.
Polijel 220 is an isophtalic/NPG/special based, acrylic modified, thixotropic, pre-accelerated gelcoat.
It is designed for the production of mould for polyester products.
The most important feature of gelcoat is it's resistance to ageing effects of release agents and styrene.
It has optimal flexibility and advanced stroke resistance.

NORPOL® SVG is a family of high-quality gelcoats based on a premium ISO/NPG polyester resin.
APPLICATION
NORPOL® SVG gelcoats are available in both spray and brush versions.
• Recommended peroxide dosage: 1.3 - 2.0%
• Recommended film thickness: 0.55-0.85 mm (wet film)
FEATURES AND BENEFITS:
NORPOL® SVG Gelcoats can provide a significant reduction in emission of volatiles. White spray gelcoat has a VOC content of ca. 30 wt% whilst white brush gelcoat contains only ca. 25 wt%.
The VOC emissions of NORPOL® SVG products are approximately 50 percent lower than those of conventional gelcoats where styrene is the only monomer used.
• Excellent weathering performance
• Excellent mechanical properties/ improved surface aesthetics
• Easy to apply: processing robustness enables high quality manufacturing
• Applications include sanitary components, boats, car bodywork, cladding panels, etc.
